Re: iPod + Video and Archive MPEG4 Files |
Yay! A new mp4 success on ipod, woot! 8-D
Yes, so we had an intern who brilliantly figured out how
to solve most of our audio problems by simply using
"mplayer" to dump the audio as a stereo WAV track.
Since mplayer can play pretty much anything, this meant
that most of our "audio problems" suddenly got fixed.
Better yet, instead of the 3-4 audio pass encodings just
to get the WAV/PCM format, it's all done in one quick
mplayer command now.
I then hooked it all up, fixed up some "encode to mpg audio"
settings, and there it is!
Lastly, I tossed 15 of the worst and most difficult items
I knew at it and rederived them (they had horrible or
completely gone audio in the derived mp4s). To my utter
shock and delight, all worked.
As I personally love moving images, I'm glad we finally got
a lot of this audio stuff fixed!
mp4 files aren't the easiest to "get right" -- they're not
like the supereasy MPG1 and MPG2 formats, unfortunately.

Re: iPod + Video and Archive MPEG4 Files |
I have also been having trouble with my iPod video in two ways, but maybe this will help:
1. Some films that I used iSquint to convert (I have grabbed some of the larger mpeg files that need conversion before they are dropped into iTunes,) and they have a flaw in that the video/audio will freeze, and then restart with no audio. Apparently this is a flaw with the iPod 1.1 updater.
2. Some of the 256k/Mp4 files will play fine in Quicktime or in iTunes, but on the iPod they produce a clicking/digi-distortion periodically. This may also be related to the updater issue, BUT, I had no trouble with the "Night of the Living Dead" mp4 file that was posted, so maybe that answers something. Also, as a pure side note, when I have ripped PD stuff from DVD (I use Mac, so Mac the Ripper is a nice option,) then convert to Mp4 with Handbrake it seems to work well. Just laying everything I know out there. Hopefully we can all help each other.
